Hereinafter, the sunshade 10 according to the embodiment will be described (see FIGS. 1 and 2).

The sunshade 10 is a device for shielding the window 1. The shading device 10 is disposed inside the window peripheral member 3 on which the slit 4 is formed, and is configured to take out and store the sunshade 20 through the slit 4 (see FIG. 3). And the sunshade 10 is comprised so that the slit 4 may be totally blocked in the storage state of the sunshade 20 (refer FIG. 5).

For convenience, the window 1 to which the sunshade 10 is applied will be described.

Here, an example in which the sunshade 10 is applied to the window 1 that is the rear window of the vehicle is described. This window 1 is formed in the substantially equilateral trapezoidal shape which has the opposing short side and long side.

The shading device 10 is a rear package tray as a window peripheral member 3 located on the long side of the window 1 (bottom side of the vehicle) (inner materials such as trim in the case of a hatchback type). It is excreted inside of. The window peripheral member 3 is provided with a slit 4 for pulling out the sunshade 20 to be opened into the vehicle compartment. This slit 4 is formed in the shape of the narrow through-hole which extends substantially linearly along the width direction of a vehicle body. Hereinafter, for convenience of description, the width direction of the vehicle body is referred to as the longitudinal direction of the slit 4 with respect to the slit 4, and the direction orthogonal to the longitudinal direction (direction of the short dimension) is referred to as the width direction. More specifically, the slit 4 has a dimension substantially the same as the long side of the window 1 in the longitudinal direction (a dimension larger than that of the long side end 24 in relation to the sunshade 20 to be described later). It is set. In addition, the width dimension of the slit 4 is set to the dimension of the grade which can arrange | position the stay 40 mentioned later inside.

Of course, the sunshade 10 is not limited to the rear window of an automobile as described above, but can also be applied to other windows such as a side window of an automobile. When applied to these windows, the sunshade 10 is disposed inside the trim as the window peripheral member, other interior materials, and the like, and the slit may be formed in each part.

The sunshade 10 includes a sunshade 20, a winder 30, a stay 40, a cover 50, and an interlock mechanism 60.

The sunshade 20 is formed in the size and shape which can shield the window 1 by cutting, sewing etc. cloth | cover materials, a resin sheet, etc., such as a mesh shape. More specifically, the sunshade 20 is formed in a shape having an opposite short side end 22 and a long side end 24 (here, an approximately equilateral trapezoidal shape). Moreover, the edge part of both sides which connects the short side edge part 22 and the long side edge part 24 of the sunshade 20 is called side end part 26 (refer FIG. 1, FIG. 2).

Of course, the sunshade 20 has a short side end portion 22 and a long side end portion 24, and if the window 1 can be shielded, a trapezoidal shape other than an equilateral trapezoid, or a side end portion has a shape such as a curve or the like. It may be.

The sunshade 20 is mounted to the take-up device 30 so that it can be taken out and stored. The winding device 30 has a base 32, a rotation support part 33, a winding shaft 34, and the like.

The base 32 is a member formed by cutting or bending a metal plate, or a member formed by extruding a metal.

The winding shaft 34 is a long cylindrical member, and is rotatably supported about the axis by the rotation support part 33 with respect to the base 32. The long side edge part 24 of the sunshade 20 is attached to the outer peripheral surface of this winding shaft 34 along the axial direction. As a result, when the winding shaft 34 is rotated, the sunshade 20 is wound around the winding shaft 34.

In addition, the winding shaft 34 rotates in the direction (winding direction R) which winds the sunshade 20 with respect to the rotation support part 33 by the biasing member (coil spring etc.) which are not shown in figure.付 勢) is.

The winding device 30 is disposed inside the window peripheral member 3 located on the long side of the window 1. And the position of this winding-up device 30 is arrange | positioned in the position which can pull out the awning 20 wound up by the winding shaft 34 to the inside of a compartment through the slit 4. As shown in FIG. The winding device 30 is supported at the position by fixing the base 32 to a vehicle body, a panel of a door, or the like by screwing or the like.

The stay 40 for pulling out the sunshade 20 is attached to the short side end 22 of the sunshade 20 (see FIGS. 1 and 2). The stay 40 is a long rod-shaped member which reaches the full length of the short side edge part 22 of the sunshade 20. Here, the stay 40 is formed in the substantially same dimension as the short side edge part 22 of the sunshade 20.

In the state where this stay 40 is not taken out, the awning 20 is maintained in the storage state wound by the winding shaft 34 by the winding force of the winding device 30 (refer FIG. 2, FIG. 5). In this state, the stay 40 is disposed inside the slit 4 (a position surrounded by the opening edge of the slit 4), and the slit 4 is partially in the longitudinal direction (here, the central portion). It is supposed to prevent.

Here, the state in which the stay 40 blocks the slit 4 is not limited to the state in which the slit 4 is completely covered in the width direction, and also includes the internal structure (winding device 30) of the window peripheral member 3. Should be blocked enough to hide from the outside. Preferably, the size relationship between the stay 40 and the slit 4 is the slit 4 on the plane where the opening edge of the slit 4 is located, with the stay 40 disposed in the slit 4. It is sufficient that the stay 40 is slightly narrower in width than the width dimension.

The stay 40 is fixed to a part of the winding device 30 at a position disposed in the slit 4 so that winding can be regulated so that the sunshade 20 is no longer wound. For example, the winding device 30 may be provided with a stopper (not shown) for fixing the stay 40. Of course, the stay 40 may be made to regulate the winding of the sunshade 20 by fixing to the part of the window peripheral member 3.

In addition, the awning 20 can be pulled out through the slit 4 by manipulating the stay 40 in a direction substantially perpendicular to the axial direction of the winding shaft 34 against the winding force of the winding device 30. . Here, the sunshade 20 is drawn out along the window 1. And the direction in which the shade 20 is taken out and received is referred to as the withdrawal storage direction (P). The state in which the sunshade 20 is pulled out until the entire window 1 is shielded is referred to as the sunshade 20 (see FIGS. 1 and 3).

As described above, in the sunshade 10 using the sunshade 20 having the short side end 22 and the long side end 24, the long side end 24 (the slit 4 in the sunshade 20 pulled out state). The slit 4 is formed longer than the long side edge part 24 in the form which can pass the part located in the inside. On the other hand, the stay 40 is formed corresponding to the short side edge part 22 smaller than the long side edge part 24 of the sunshade 20.

For this reason, in the sunshade 20 storage state, the location which is not blocked by the stay 40 arises in the longitudinal side (here both sides) position of the stay 40 arrange | positioned in the slit 4. Thereby, the slit 4 will remain in the state opened partially by the length longer than the stay 40 also in the shading 20 storage state.

Therefore, in the sunshade 10, the structure that can block the whole slit 4 in the sunshade 20 storage state is employ | adopted.

Moreover, as mentioned above, this subject originates in the shape of the sunshade 20 which has the short side edge part 22 and the long side edge part 24, and is not directly related to the shape of the window 1. As shown in FIG. That is, although the awning 20 is normally formed in the shape corresponding to the shape of the window 1 (in the form of a trapezoid or trapezoid), even if it is a window which does not have a short side and a long side, the short side edge part 22 And a sunshade 20 having a long side end 24 may be used. That is, the sunshade 10 can also be applied to a window having a shape other than the shape having the short side and the long side described above.

Hereinafter, the structure which blocks the slit 4 as a whole in the sunshade 20 storage state is demonstrated.

The cover body 50 is comprised so that a movement is possible between the closed position which partially blocks the slit 4, and the open position which opens the slit 4 (refer FIG. 7, FIG. 8). More specifically, the closed position of the cover body 50 is a position of blocking the longitudinal side of the stay 40 in the sunshade 20 storage state among the slits 4, and the open position is the sunshade 20 in the pulled out state. It is the position which retracted from the closed position so that it may not interfere with the side end part 26 of the. That is, the open position of the cover body 50 is not limited to the state which did not block the slit 4 at all.

Here, the slit 4 is blocked by the stay 40 and the cover body 50 in the sunshade 20 storage state (see FIG. 5). That is, since the stay 40 is comprised so that the center part of the slit 4 may be blocked in the sunshade 20 storage state, it is set so that the opening part of both sides of the stay 40 of the slit 4 may be blocked, respectively. Cover bodies 50 are provided.

Of course, the cover body 50 should just cover the part open | released in the longitudinal direction side of the stay 40 of the slit 4 in the sunshade 20 storage state. That is, when the stay 40 is disposed close to one side in the longitudinal direction of the slit 4 in the sunshade 20 receiving state (for example, a sunshade formed in a trapezoid in which one angle forms a right angle) In the case), it may be provided only on the other side in the longitudinal direction of the stay 40. In addition, the number of the cover bodies 50 of the interlock mechanism 60 mentioned later is determined by the number.

This cover body 50 is a member in which the main body portion 52 and the guide portion 56 are integrally formed by a resin material or the like.

The main body part 52 is formed in the shape which can block the location opened to the longitudinal direction side of the stay 40 arrange | positioned in the slit 4 in the sunshade 20 storage state. Here, the main body portion 52 is formed in a flat shape having a width dimension equal to or larger than the width dimension of the slit 4 (here, large). Moreover, what is necessary is just to form the main-body part 52 in the surface shape made to follow the in-vehicle side part of the window peripheral member 3 in the state which closed the slit 4.

The guided portion 56 is formed to be connectable to the following interlock mechanism 60 so that the main body portion 52 is moved between the open position and the closed position.

The interlock mechanism 60 is comprised so that the cover body 50 can be moved between an open position and a closed position in conjunction with the rotation of the winding shaft 34. That is, the interlock mechanism 60 can move the cover body 50 in accordance with the draw-out operation of the sunshade 20. And the interlock mechanism 60 is comprised so that the cover body 50 may be moved to the closed position by the stay 40 and the cover body 50 in the state which accommodates the awning 20 in the state which accommodated the slit 4. have.

Here, the interlock mechanism 60 is comprised so that the cover body 50 can move along the axial direction of the winding shaft 34. As shown in FIG.

In addition, since two cover bodies 50 are provided as mentioned above here, two interlock mechanisms 60 which operate each cover body 50 are provided, respectively. In addition, in the following description, it demonstrates paying attention to the cover body 50 and the interlocking mechanism 60 of one side (refer FIG. 4, FIG. 6-FIG. 9). The same applies to the configuration on the other side.

The interlock mechanism 60 has a guide 62 and a transmission means.

Guide body 62 is a rod-shaped member in which a spiral guide groove 63 is formed in an outer circumferential portion and is rotatable about an axis (see FIGS. 7 and 8). Here, the guide body 62 is a screw gear in which a tooth groove is used as the guide groove 63.

On the other hand, the guide part 56 of the cover body 50 has the protrusion part 57 which can move inside the guide groove 63 of the guide body 62. More specifically, the guide part 56 is formed in the form which protrudes from the one end part of the cover body 50 in the moving direction in the back surface of the main body part 52, and is a hole which penetrates in the said moving direction. Have wealth The hole is formed so that the guide body 62 can be inserted (slightly larger than the outer diameter of the guide body 62). And the protrusion part 57 is formed in the form which protrudes toward the radial inside from the inner peripheral part of a hole part. Here, the guide part 56 has the form with the female threaded part corresponding to the guide body 62 which is a screw gear, and the mountain part of the said female thread is the protrusion part 57 (refer FIG. 9).

Of course, the protrusion part 57 of the to-be-guided part 56 is not limited to the female threaded part, For example, the protrusion part 56 which protrudes in a columnar shape and a hemispherical shape from one part of a hole part may be sufficient. . That is, the protrusions 57 may be disposed in the guide grooves 63 of the guide body 62, and may be moved inside the guide grooves 63 (guided) in such a state of excretion.

In the state where the guide body 62 is inserted into the guided part 56, the protrusion 57 of the guided part 56 is disposed in the guide groove 63 of the guide body 62. When the guide body 62 is rotated relative to the guided portion 56, the protrusion 57 moves in the guide groove 63, so that the cover body 50 is in the axial direction of the guide body 62. Move relative to

The axial dimension of the part in which the guide groove 63 is formed in the guide body 62 is set so large that it can guide the cover body 50 between an open position and a closed position. That is, the dimension is equal to or equal to the dimension obtained by adding the movement distance between the open position and the closed position of the cover body 50 and the size of the guide portion 56 in the moving direction of the cover body 50. It may be set longer than that (longer here).

The guide body 62 is not limited to a screw gear, and may be a rod-shaped member in which a helical cam groove is formed as the guide groove. That is, the shape in which the spiral cam groove (guide groove) set in the torsion angle in each part is formed also can be employ | adopted, and even if the side end part of the sunshade 20 is a curved shape etc., it is a cover body along the said side end part. 50 can be moved. In this case, as the shape of the protruding portion of the guided portion 56, the above-described cylindrical shape, hemispherical shape or the like may be adopted.

The path setting of the guide groove 63 of the guide body 62 will be described later along with the description of the linkage operation between the draw-out storing of the sunshade 20 and the opening / closing movement of the cover body 50.

The transmission means is comprised so that the axial rotational force of the winding shaft 34 can be transmitted as the axial rotational force of the guide body 62. This transmission means has the winding shaft side gear 36, the interlocking gear 64, and the intermediate gear 66. As shown in FIG.

The winding shaft side gear 36 is connected relative to the winding shaft 34 on a coaxially incapable of relative rotation. Here, the winding shaft side gear 36 is integrally comprised in the edge part of the winding shaft 34, and is rotatably supported by the rotation support part 33 with the winding shaft 34 so that rotation about the axis is possible.

The interlocking gear 64 is connected to the guide body 62 on the coaxial axis in a non-relative manner. Here, the guide body 62 and the interlocking gear 64 are integrally formed.

The guide 62, the interlocking gear 64, and the intermediate gear 66 are supported by a gear holder 68 placed on a support 38 constituting the winding device 30. More specifically, the gear holder 68 supports the guide body 62, the interlocking gear 64, and the intermediate gear 66 in such a manner that the interlocking gear 64 and the intermediate gear 66 mesh with each other. In addition, in FIG.7 and FIG.8, the part which supports the intermediate gear 66 among the gear holders 68 is shown by the dashed-dotted line.

In this case, the intermediate gear 66 may be configured to be interchangeable with one having a different size corresponding to the window 1 to which the sunshade 10 is applied. For example, the intermediate gear 66 can employ | adopt the structure which can be replaced integrally with the part of the gear holder 68 supported. That is, what is necessary is just to comprise the part shown by the dashed-dotted line in FIG.7 and FIG.8 so that attachment or detachment is possible by fitting, screwing, etc. to another part of the gear holder 68. FIG.

This support body 38 is comprised so that attachment and detachment with respect to the base 32 are possible. More specifically, the support 38 is mountable with respect to the base 32 at a position such that the intermediate gear 66 is engaged with the take-up shaft side gear 36. Preferably, the support 38 may be mounted in such a manner that the intermediate gear 66 meshes with the take-up shaft side gear 36 even when the intermediate gear 66 is replaced as described above. For example, the support body 38 should just be removable by the structure which can be fixed to the base 32 by fitting, screwing, etc.

In addition, when the winding shaft 34 is rotated in the winding direction R, the guide body 62 moves the cover body 50 toward the closed position side, and the winding shaft 34 is wound in the winding direction R. As shown in FIG. When rotated in the reverse direction, the cover member 50 is supported by the gear holder 68 in a position to move the cover body 50 toward the open position. That is, this posture is a posture in which the path of the guide groove 63 becomes a spiral shape turning in the winding direction R toward the longitudinal direction outer side of the winding shaft 34.

Moreover, as for the cover body 50, the edge part of the side in which the guide part 56 is formed is located in the longitudinal center side of the winding shaft 34 in the state in which the support body 38 was attached to the base 32, What is necessary is just to be connected to the guide body 62 in the posture (refer FIG. 7, FIG. 8). Thereby, since the guide body 62 can be arrange | positioned at the longitudinal center side of the winding shaft 34, it can also be arrange | positioned at the center side as the whole interlocking mechanism 60, and the longitudinal direction of the shading device 10 is carried out. The dimensions can be made compact.

The interlock mechanism 60 is configured to move the cover body 50 in the closed position in the sunshade 20 storage state, and move the cover body 50 in the open position in the pull-out state of the sunshade 20. have. More specifically, the interlock mechanism 60 is configured to gradually move the cover body 50 between the open position and the closed position in accordance with the draw-out operation of the sunshade 20. Preferably, the interlock mechanism 60 passes the cover body 50 along the side end portion 26 of the sunshade 20 to be drawn out and stored (in other words, passes through the side of the cover body 50). What is necessary is just to set so that the space | interval may be kept substantially constant with respect to the side end part 26 of the sunshade 20.

The interlocking operation of the draw-out storing of the sunshade 20 and the opening / closing movement of the cover body 50 includes the path of the guide groove 63 of the guide body 62, the winding shaft side gear 36 and the intermediate gear 66. ) And the reduction ratio of the winding shaft 34 and the guide body 62 determined by the interlocking gear 64.

That is, the movement form (the ratio of the movement amount in the angular position with respect to the total movement amount) between the opening position and the closing position of the cover body 50 according to the draw-out storing (rotation of the winding shaft 34) of the sunshade 20. ) Is determined by the torsion angle of the guide groove 63 path. The path of the guide groove 63 is a shape of the side end portion 26 of the sunshade 20 (in other words, the inclination angle with respect to the short side end 22 and the long side end 24 at each position of the side end 26). Is determined on the basis of

Moreover, the reduction ratio of the winding shaft 34 and the guide body 62 is determined based on the maximum withdrawal amount of the sunshade 20. Here, the reduction gear ratio may be changed by replacing the intermediate gear 66 with one having a different dimension. Of course, the reduction ratio may be changed by replacing the take-up shaft side gear 36 and the interlocking gear 66.

The structure of the interlock mechanism 60 is not limited to the said form. For example, the transmission means may be configured so that the take-up shaft side gear 36 and the interlocking gear 64 directly engage with each other without passing through the intermediate gear 66. In this case, the guide body 62 may be supported by the gear holder 68 in a posture in which the path of the guide groove 63 becomes a spiral shape opposite to the above.

In addition, the transmission means may interlock the winding shaft 34 and the guide body 62 at a reduction ratio determined according to the shape and size of the window 1 to which the sunshade 10 is applied. Branch configurations can be employed. For example, the transmission means may have a configuration in which a pulley connected to the winding shaft 34 and a pulley connected to the guide body 62 interlock with each other via a belt.

Moreover, the cover body guide part 39 which guides the cover body 50 to a movement direction is formed in the support body 38 (refer FIG. 7, FIG. 8). Here, the cover body guide part 39 is one short side part along the moving direction of the flat-shaped main-body part 52 in the state which inserted the guide body 62 into the to-be-guided part 56 here. It is formed in the groove shape which can excrete. In other words, the cover body guide portion 39 is capable of regulating the rotation of the cover body 50 around the axis of the guide body 62, and can be contacted on both sides in the thickness direction of the one short side portion (one short side thickness dimension). Slightly wider).

Of course, the structure which guides the cover body 50 is not limited to the above. That is, while the protruding cover body guide part is formed in the support body 38, the groove part which can arrange | position this protruding cover body guide part inside may be formed in the main-body part 52. As shown in FIG.

In addition, the support body 38, the gear holder 68, the guide body 62, the interlocking gear 64, the intermediate gear 66, and the cover body 50 described above are attached to and detached from the base 32. It can be handled as an integral part if possible.

In addition, the stay 40 is an auxiliary cover portion 48 extending in the longitudinal direction at a position deviating from the take-out storage direction P of the shade 20 with respect to the cover body 50 in the shade 20 storage state. ) (Indicated by two-dot chain lines in FIGS. 6 and 7). More specifically, the stay 40 has end members 42 at both ends, and the auxiliary cover portion 48 is configured to extend outward in the longitudinal direction from the angle end members 42.

The cover body 50 described above is provided in such a manner that it does not interfere with the side end portion 26 of the sunshade 20, so as not to interfere with the stay 40 during the draw-out operation of the sunshade 20. It is prepared. For this reason, in the sunshade 20 accommodating state, some space | interval arises between the end member 42 of the stay 40, and the cover body 50. As shown in FIG. That is, the auxiliary cover part 48 is provided in order to prevent the end member 42 of the slit 4 from the cover body 50 in the sunshade 20 accommodating state.

Here, the auxiliary cover part 48 is an end member so that the auxiliary cover part 48 overlaps with respect to the inner end part of the cover body 50 in the closed position in the sunshade 20 in the withdrawal-receiving direction P of the sunshade 20. It extends from (42). Thereby, in the storage state of the sunshade 20, the slit 4 seen from the inside of the cabin is blocked with no space | interval between the stay 40 and the cover body 50. FIG. The auxiliary cover portion 48 may be formed in a flat plate shape along the inboard portion of the window peripheral member 3 in the sunshade 20 storage state.

Hereinafter, the movement operation of the cover body 50 according to the draw-out operation of the sunshade 20 will be described.

First, the operation at the time of taking out the sunshade 20 will be described. As the initial state, it is assumed that the sunshade 20 is in a stored state (see FIGS. 2 and 5 to 7). That is, the slit 4 is in the state blocked by the stay 40 and each cover body 50 located in the closed position.

First, the stay 40 located in the slit 4 is moved along the window 1 to the withdrawal storage direction P withdrawal side.

When the stay 40 is moved and the shade 20 starts to be pulled out, the winding shaft side gear 36 rotates in the opposite direction to the winding direction R together with the winding shaft 34 on which the shade 20 is wound. And with the rotation of the take-up shaft side gear 36, the guide body 62 is rotated in the opposite direction to the take-up direction R together with the interlocking gear 64 via the intermediate gear 66.

Then, the cover body 50 in the closed position is gradually moved toward the open position side (the longitudinal direction outer side of the winding shaft 34) by the rotation of the guide body 62. More specifically, the cover body 50 is position-controlled in the circumferential direction of the guide body 62 by the cover body guide part 39, and the protrusion 57 is the circumference of the guide body 62. The guide groove 63 is moved by the rotation of the guide body 62 while being positioned at a substantially constant position in the direction. Thereby, the cover body 50 is moved to a fixed attitude.

As the shade 20 is further pulled out, the width dimension of the portion of the shade 20 located in the slit 4 gradually increases. The cover body 50 also gradually moves from the closed position side to the open position side in such a manner as to avoid the sunshade 20. That is, while the gap between the side end portion 26 of the sunshade 20 and the end of the inner side of the cover body 50 (the longitudinal center side of the winding shaft 34) is almost constant, the sunshade 20 is drawn out and the cover body ( 50) moves.

When the sunshade 20 is pulled out to the position (drawing state) which shields the window 1 as a whole, the long side end part 24 side part of the sunshade 20 is located in the slit 4 in the longitudinal direction as a whole, and the cover body ( 50) is located in the open position. In other words, the slit 4 is in an open state as a whole.

Next, the operation at the time of storing the sunshade 20 will be described.

When the stay 40 is moved to the drawer storing direction P storage side, the sunshade 20 is wound up by the winding force of the winding-up device 30, and is accommodated. The winding shaft side gear 36 is rotated together with the winding shaft 34 that is rotated in the winding direction R in accordance with the winding of the sunshade 20. And with the rotation of the take-up shaft side gear 36, the guide body 62 is rotated around the axis along the interlocking gear 64 via the intermediate gear 66 in the take-up direction R. As shown in FIG.

Then, the cover body 50 in the open position is gradually moved toward the closed position side (the longitudinal direction inner side of the winding shaft 34) by the rotation of the guide body 62.

When the stay 40 is further moved to the storage side, the dimension of the portion of the sunshade 20 located in the slit 4 in the longitudinal direction of the slit 4 gradually decreases. The cover body 50 also gradually moves from the open position to the closed position. At this time, the cover body 50 moves while the sunshade 20 is accommodated while the gap between the side end portion 26 of the sunshade 20 and the inner end of the cover body 50 is substantially constant, as in the case of withdrawal.

When the stay 40 is moved to a position where the stay 40 is disposed in the slit 4 (the stay 40 is fixed to a part of the winding device 30), the sunshade 20 is in a stored state, and the cover body 50 is Located in the closed position. That is, the slit 4 is in the state clogged by the stay 40 and the two cover bodies 50 as a whole.

The shading device 10 may be a manual operation of the stay 40. Here, the shading device 20 is moved by the drive mechanism 90 to move the stay 40 through the pair of arms 80. It is configured to automatically withdraw and store (see Figs. 1 and 2).

The pair of arms 80 each have a first member 82 and a second member 84.

One end of the first member 82 and the other end of the second member 84 are connected so as to be relatively rotatable (second connection portion C2). Moreover, a part of the other end side of the 1st member 82 is connected so that relative rotation is possible with respect to the end side part of the base 32 of the winding apparatus 30 (1st connection part C1). In addition, one end of the second member 84 is connected to the end member 42 of the stay 40 so as to be relatively rotatable (third connecting portion C3). For example, as each connection part C1-C3, the structure which connects a connection object can be employ | adopted by inserting a connection shaft member into the through-hole part formed between connection objects.

That is, the pair of arms 80 pulls the stay 40 out of the shade 20 by being folded (see FIG. 2) and unfolding (see FIG. 1) at the second connecting portion C2 position. It is comprised so that a movement operation is possible in the storage direction P. FIG.

More specifically, the first member 82 extends from the first connection portion C1 toward the side of the window 1 in the deployed state of the arm 80. ) 83a and a flat rod-shaped member 83b which extends along the side of the window 1 in a form bent from one end of the frame directing portion 83a. In addition, the second member 84 is a substantially straight flat plate-shaped member.

That is, when the second connecting portion C2 moves inward in the longitudinal direction of the winding device 30 and the pair of arms 80 are folded, the stay 40 is moved from the short side of the window 1 to the long side. The sunshade 20 is stored and operated. And the sunshade 20 is in a retracted state in the folded state in which the arm 80 is completely folded.

In addition, when the second connecting portion C2 moves outward in the longitudinal direction of the winding device 30 and the pair of arms 80 are deployed, the stay 40 is moved from the long side of the window 1 to the short side. The sunshade 20 is pulled out. The arm following the arm 80 in which the frame follower 83b and the second member 84 of the first member 82 are in a straight line shape, and the sunshade 20 covers the entire window 1. do.

The drive mechanism part 90 is comprised so that rotation drive of the 1st member 82 of the arm 80 can be carried out around the 1st connection part C1. Here, the drive mechanism part 90 has the motor 92 and the predetermined | prescribed link 94 connected to the other end part rather than the 1st connection part C1 of the 1st member 82. As shown in FIG. That is, the drive mechanism part 90 is comprised so that the motor 92 may rotationally drive the angle 1st members 82 of the pair of arms 80 via the predetermined link 94. Thereby, the pair of arms 80 can be unfolded and folded to move the stay 40 in the takeout storage direction P of the sunshade 20, and the sunshade 20 can be pulled out and stored.

This drive mechanism 90 may be provided so that the drawing operation part which is not shown in figure which can operate the drive of the motor 92 is provided, and draw-out storage drive by operation of the said operation part.

Of course, the sunshade 10 is not limited to the above configuration. For example, the sunshade 10 may be such that the cover body is moved by a rack and pinion mechanism. That is, the rack is provided in the cover body along the moving direction, and the interlock mechanism has a pinion engaged with the rack, a winding shaft side gear and an intermediate gear installed to transmit the axial rotational force of the take-up shaft as the axial rotational force of the pinion. For example, a structure having a bevel gear combination) can be adopted.

In addition, the sunshade 10 is not limited to the structure in which the 1st member 82 of the arm 80 has the frame directing part 83a and the frame following part 83b. For example, like the sunshade 110 shown in FIGS. 10 and 11, the arm 180 has a structure in which the first member 182 and the second member 184 having a substantially linear shape are connected to each other. In the unfolded state, the first member 182 and the second member 184 may be configured to have a substantially straight line shape as a whole. The sunshade 110 having the configuration shown in FIGS. 10 and 11 has the same configuration as the sunshade 10 described above except for the arm 180 configuration.

In addition, the sunshade 10 may be provided with the interlock mechanism comprised so that a cover body can move along the direction orthogonal to the axial direction of the winding shaft 34. As shown in FIG. That is, it has a guide body rotatable about an axis along the width direction of the slit 4, and is configured to transmit the axial rotational force of the take-up shaft 34 as the axial rotational force of the guide body via the transmission means. For example, the transmission means may adopt a configuration having a take-up shaft-side gear, an interlocking gear that is coaxially incapable of relative rotation with the guide body, and a bevel gear that meshes with the take-up shaft gear and the interlocking gear.

In the case where the cover body is moved along the direction orthogonal to the axial direction of the winding shaft 34, a part of the side end portion 26 of the sunshade 20 is closed in the closed position from the start of withdrawal of the sunshade 20. Before contacting the inner end of the cover body 50, it is preferable that the cover body is retracted from the path of the sunshade 20, and after being evacuated, the cover body is kept in the retracted position until the sunshade 20 is completely pulled out. .

For example, as a guide body, the retraction guide part which has the guide surface inclined with respect to the circumferential part in the outer peripheral part, and the holding guide part which has the guide surface along the circumferential direction continuously in the one end part of the said inclination part are formed in the outer peripheral part. The structure of cylindrical shape or cylinder shape can be employ | adopted. That is, when the cover body is in the closed position, the protrusion of the cover body is located at the other end of the retracting guide portion, and when the shade 20 is drawn out and the winding shaft 34 starts to rotate, the projecting portion is guided to the retracting guide portion. The cover body retracts from the path of the sunshade 20 before the side end portion 26 of the sunshade 20 contacts the inner end of the cover body 50 in the closed position. Thereafter, the protruding portion of the cover member is guided to the holding guide portion, and is held at an approximately constant open position in the axial direction of the guide member during the extraction operation of the sunshade 20.

As mentioned above, according to the structure which moves a cover body along the direction orthogonal to the axial direction of the winding shaft 34, the winding apparatus 30 can be provided in the full width direction of the installation space.

According to the shading device 10 configured as described above, the cover 50 prevents the portion of the slit 4 that is open even in the storage state of the shading 20 (a part which cannot be blocked by the stay 40). Consists of. Then, the cover body 50 is moved between the open position and the closed position in association with the rotation of the take-up shaft 34 by the interlock mechanism 60, so that the stay 40 and the closed position are in the stored state of the shade 20. The slit 4 is prevented by the cover body 50 moved to. For this reason, the slit 4 can be totally blocked in the storage state of the sunshade 20. In addition, since the cover body 50 moves to the open position in the pulled-out state of the sunshade 20, interference with the sunshade 20 of the cover body 50 can also be prevented.

In addition, since the interlock mechanism 60 is configured to operate the cover body 50 in conjunction with the rotation of the take-up shaft 34, the slit 4 can be easily provided only by the draw-out storing operation of the sunshade 20. Can be opened and closed.

In addition, since the cover body 50 is provided on the winding device 30 side, the weight of the stay 40 itself is increased compared with the case where the structure for blocking the slit 4 as a whole is provided in the stay 40. I can do it lightly. Thereby, it is required to improve the strength of the structural members such as the base 32 of the winding device 30 on which the pair of arms 80, the connecting portions C1 to C3, and the pair of arms 80 are supported. There is also an advantage that the member change can be omitted. In addition, the cost of the change can be omitted. And since the weight of the stay 40 becomes small, the load on the drive mechanism part 90 can also be reduced.

Moreover, since the structure of the stay 40 can be simplified, problems, such as a latch, can be suppressed at the time of taking out and storing the shade 20.

Moreover, since it is comprised so that the cover body 50 may move along the axial direction of the winding shaft 34, even if it is difficult to ensure space in the direction orthogonal to the axial direction of the winding shaft 34, it is applicable. Can be. And since there is no operation | movement which made the cover body 50 protrude toward the inside of a vehicle, it can avoid that the cover body 50 overlaps inside the vehicle side of the window 1 at the time of withdrawal of the shade 20.

In addition, when the circumferential rotational force of the winding shaft 34 is transmitted by the transmission means and the guide body 62 is rotated about the axis, the protrusion 57 moves in the guide groove 63 of the guide body 62. The cover body 50 is moved relative to the guide body 62 in the axial direction. For this reason, by setting the path of the guide groove 63 according to the shape of the sunshade 20, the maximum withdrawal amount, etc., the cover body 50 is interlocked with the rotation of the winding shaft 34 in accordance with the withdrawal and storage operation of the sunshade 20. I can do the opening and shutting movement of hope for).

In addition, since the take-up shaft side gear 36 which rotates integrally with the take-up shaft 34 and the interlocking gear 64 which rotates integrally with the guide body 62 are rotated through the intermediate gear 66, the cover body is rotated. The design change, such as the movement amount of 50, can be made by changing the intermediate gear 66, which also has the advantage of high design freedom.

In addition, since the guide body is a screw gear, the cover body 50 can be moved with a constant moving amount with respect to the rotation amount of the winding shaft 34. That is, when the side end portion 26 of the sunshade 20 has a straight shape, the sunshade 20 is stably maintained while maintaining a constant distance between the cover body 50 and the side end portion 26 of the sunshade 20. Withdrawal storage operation can be performed.

Moreover, since the cover body guide part 39 is provided in the winding device 30, the movement and attitude | position of the cover body 50 other than the axial direction (axial direction of the winding shaft 34) of the guide body 62 are moved. By restricting the change, the operation of the cover body 50 can be stabilized.

Moreover, since the auxiliary cover part 48 is provided in the stay 40, the whole slit 4 can be blocked more reliably by the stay 40 and the cover body 50. As shown in FIG.

Although the sunshade 10 has been described in detail as described above, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that a myriad of modifications which are not illustrated can be assumed without departing from the scope of the invention.
